Like the rule 'Set multiple fields', we would lik to have a rule 'Hide multiple fields'. We make a lot of, and too many, hide field rules, especially in the offerings.
I agree that it would be much better to replace all single field rules by multiple field versions.
We can even get rid of single fields ones (like hide field, disable field and even set field) by replacing them automatically with their multiple field versions. It would give a cleaner more consistent set of rules.
